Silver‐Catalyzed Functionalization of Esters by Carbene Transfer: The Role of Ylide Zwitterionic Intermediates. Issue 8 (2nd July 2014) - Gava, Riccardo
Abstract The reaction of esters with ethyl diazoacetate catalyzed by the complex [F27–Tp 4 Bo, 3 CF 2CF 3Ag(acetone)] generates α‐(acyloxy)acetates in moderate to high yields. This is a novel transformation in the context of carbene‐transfer reactions from diazo compounds that, according to experimental and theoretical data, is suggested to occur through zwitterionic intermediates.
